Im trying to migrate my emummc from my 64gb card to my 256 gb card so I backed up the emummc as 2gb partials and I would like to restore this backup on my new sd card and have everything be the same on it. I am seeing though that you need to actually use a joiner script to combine it into a rawnand but I cant run that since I am on chromebook. can I do it as individual parts instead as a migration
